Anything that is fast and quick is good for the chick- To keep it from suffering- I think the hardest part of a lot of methods are the feelings of the human caregiver. Growing up on around farms, Usually small animals were "knocked in the head" with a hammer or club. There is nothing wrong with doing it that way as it is quick and very effective for small animals. Larger grown animals were usually taken out with a bullet behind the ear or in between the eyes. But many people didn't grow up having to do stuff like this and it's just too hard on them to use a "violent" (for lack of a better word) method. Part of being a responsible caretaker of pets and livestock is to be able to put them out of misery when you have no other choice. It's never going to be easy or pretty but it's part of the lifestyle. It's not always easy and you can't run to the vet every time this comes up unless you have a fortune to spend. The hard part is the decision to do it and then getting the nerve to do it. After it's done it usually doesn't bother you that long , because you know you have done the right thing by an animal that is suffering. This forum is wonderful because you can get a lot of information on methods and support from people who have been in the same shoes . Sorry you had to go through but it comes with the territory . Luckily there are so many rewarding things about raising and caring for your animals and watching them grow that outweigh the occasional bad things.
